func_get_args — Returns an array comprising a function's argument list

Description

array func_get_args ( void )

Gets an array of the function's argument list.

This function may be used in conjunction with func_get_arg() and func_num_args() to allow user-defined functions to accept variable-length argument lists.

Return Values

Returns an array in which each element is a copy of the corresponding member of the current user-defined function's argument list.

Changelog

Version Description
5.3.0 This function can now be used in parameter lists.

Errors/Exceptions

Generates a warning if called from outside of a user-defined function.

Examples

Example #1 func_get_args() example

<?php
function foo()
{
    $numargs = func_num_args();
    echo "Number of arguments: $numargs<br />\n";
    if ($numargs >= 2) {
        echo "Second argument is: " . func_get_arg(1) . "<br />\n";
    }
    $arg_list = func_get_args();
    for ($i = 0; $i < $numargs; $i++) {
        echo "Argument $i is: " . $arg_list[$i] . "<br />\n";
    }
}

foo(1, 2, 3);
?>

Notes

Note: Because this function depends on the current scope to determine parameter details, it cannot be used as a function parameter. If this value must be passed, the results should be assigned to a variable, and that variable should be passed.

Note: This function returns a copy of the passed arguments only, and does not account for default (non-passed) arguments.
